This is a thread about series that are created by authors. This has nothing to do with publisher series which need to be dealt with separately.
• Some series are easy to number as the books might be shown with numbering, or official sources can provide this information. In this situation the first work serves as the introduction and the final work serves as the conclusion.
• Some can be numbered by publication order.
• Some can be numbered by publication order, but there might also be a suggested reading order based on internal book chronology.
• Some series are difficult to number by publication order as supplementary works might slot in between the main numbering.
• Some series can’t be numbered at all and to do so would confer sequential rank that doesn’t exist.
Therefore, it is essential that the numbering of works in a series is optional.
Most series have only one level, however many science fiction and fantasy series can have two and three sub-series. To date, I have never seen a four-tiered system. To give an example:
Honoré de Balzac wrote his opus:
La Comédie humaine (which consists of three sub-series):
• Études analytiques
• Études philosophiques
• Études de mœurs (which consists of six sub-series):
- Scènes de la vie de campagne
- Scènes de la vie militaire
- Scènes de la vie parisienne
- Scènes de la vie politique
- Scènes de la vie privée
- Scènes de la vie de province
Series can be known by various names, including language specific names for the same series, so an alias facility would be critical.
Series can be commenced by one author and continued by another author, or authors. Therefore a series can contain works contributed by multiple authors.
I would think the best way to manage series would be to enter them via the Work editor. When someone adds a Work to an Edition, then the series would be automatically added to the Edition. It would also be helpful if the Work could link to the author page and provide a summary of the series titles currently in the database.
